The last "syscfg" partition of the OEM firmware turns out to be a
UBIFS used to store user data, just as the "rootfs_data" of OpenWrt,
so it should be reasonable to absorb it into the "ubi" partition.
Factory installations via either OEM firmware or tftp, or by forcibly
flashing factory image to mtd5 (firmware) partition with mtd tool are
confirmed working, but the UBI remaining inside "syscfg" partition
could break upgrade. Fortunately, installing kmod-mtd-rw and erasing
"syscfg" partition before upgrade is confirmed working, in which case,
"ubi" will automatically expand to the blank space once occupied by
the former mtd8 (syscfg), with the total block number increased, but
the UBIFS for rootfs_data will not automatically claim the newly
available space (since it is created when mtd8 still exists, and
sysupgrade does not set "autoresize" flag to rootfs_data). These space
will be claimed during the next upgrade, when rootfs_data is removed
and created again.

From the Netgear u-boot GPL code[1]. Bootloader always unconditionally
marks block 768, 1020 - 1023 as bad blocks on each boot. This may lead
to conflicts with the OpenWrt nand driver since these blocks may be good
blocks. In this case, U-boot will override the oob of these blocks so
that break the ubi volume. The system will be damaged after first reboot.
To avoid this issue, manually skip these blocks by using "mtd-concat".

In Netgear u-boot GPL code, nand devices uses this formula to locate the
rootfs offset.
offset = (((128 + KERNEL_SIZE) / BLOCK_SIZE) + 1) * BLOCK_SIZE;
Howerver, WNDR4500 source code incorrectly define the nand block size to
64k. In some cases, it causes u-boot can't get the correct rootfs offset,
which result in boot failure. This patch workaround it by padding kernel
size to (128k * n - 128 - 1). The additional char '\0' is used to ensure
the (128 + KERNEL_SIZE) can't be divided by the BLOCK_SIZE.

Flashing instructions:
Depending on the installed firmware, there are vastly different
methods to flash a MR18. These have been documented on:
<https://openwrt.org/toh/meraki/mr18>
Tip:
Use an initramfs from a previous release and then use sysupgrade
to get to the later releases. This is because the initramfs can
no longer be built by the build-bots due to its size (>8 MiB).
Note on that:
Upgrades from AR71XX releases are possible, but they will
require the force sysupgrade option ( -F ).
Please backup your MR18's configuration before starting the
update. The reason here is that a lot of development happend
since AR71XX got removed, so I do advise to use the ( -n )
option for sysupgrade as well. This will cause the device
to drop the old AR71xx configuration and make a new
configurations from scratch.
Note on LEDs:
The LEDs has changed since AR71XX. The white LED is now used during
the boot and when upgrading instead of the green tricolor LED. The
technical reason is that currently the RGB-LED is brought up later
by a userspace daemon.

=============
LAN: from config
WiFi 1: from config
WiFi 2: +1
Installation
============
TFTP installation using UART is preferred. Disassemble the device and
connect serial. Put the initramfs image as openwrt.bin to your TFTP server
and configure a static IP of 192.168.1.100. Load the initramfs image by
typing:
setenv serverip 192.168.1.100
setenv ipaddr 192.168.1.1
tftpboot 0x82000000 openwrt.bin
bootm 0x82000000
From this intiramfs boot you can take a backup of the currently installed
partitions as no vendor firmware is available for download.
Once booted, transfer the sysupgrade image and run sysupgrade.
LTE Modem
=========
The LTE modem is probably the same as in the MF283+, all instructions
apply.
Configuring the connection using modemmanager works properly, the modem
provides three serial ports and a QMI CDC ethernet interface.

Implementation Notes
====================
Both the NOR and NAND variants boot off a NOR-based kernel,
consistent with the OEM's firmware.
The mode LEDs are
* Boot, Running system
* Failsafe 2G
* Upgrade 5G
Installation
============
Using sysupgrade
----------------
sysupgrade may be used to install a NAND image on a device running
a NAND image or a NOR image on a device running a NOR image. It is
recommended to *not* preserve config when upgrading from OEM firmware
or previous versions of OpenWrt. No supported sysupgrade path should
require "force". Transitioning from NOR to NAND can be accomplished
Using U-Boot
------------
The OEM U-Boot can be put into a graphical, firmware-upload mode by
holding down the button on the side of the router while applying power
and for a bit more than five seconds following with the current OEM
U-Boot. The power LED will come on, then the 5G LED will flash five
times, about once a second. When the 5G LED stops flashing and the
2G LED lights solid, the router's U-Boot will provide an upload page
at http://192.168.1.1/ Either a browser may be used to upload an image,
or a utility such as curl may be used:
curl -X POST -F gl_firmware=\@*-nand-squashfs-factory.img \
http://192.168.1.1/index.html
or
curl -X POST -F gl_firmware=\@*-nor-squashfs-sysupgrade.bin \
http://192.168.1.1/index.html
Note that NOR vs. NAND is based on the file name extension.

2. Reduce useless padding to shrink the size of the sysupgrade image.
3. Do not check the size of sysupgrade image. It does not make sense to
check the size of a compressed package.
4. Do not take the size of netgear header into account because it will
not be written to Flash.

Installation from Serial Console
------------
1. Connect to the serial console. Power up the device and interrupt
autoboot when prompted
2. Connect a TFTP server reachable at 192.168.1.0/24
(e.g. 192.168.1.66) to the ethernet port. Serve the OpenWrt
initramfs image as "openwrt.bin"
3. To test OpenWrt only, go to step 4 and never execute step 5;
To install, auto_recovery should be disabled first, and boot_part
should be set to 1 if its current value is not.
ath> setenv auto_recovery no

5. Copy the OpenWrt sysupgrade image to the device using scp and
install it like a normal upgrade (with no need to keeping config
since no config from "previous OpenWRT installation" could be kept
at all)
# sysupgrade -n /path/to/openwrt/sysupgrade.bin
Note: Like many other routers produced by Linksys, it has a dual
firmware flash layout, but because I do not know how to handle
it, I decide to disable it for more usable space. (That is why
the "auto_recovery" above should be disabled before installing
OpenWRT.) If someone is interested in generating factory
firmware image capable to flash from stock firmware, as well as
restoring the dual firmware layout, commented-out layout for the
original secondary partitions left in the device tree may be a
useful hint.
Installation from Web Interface
------------
1. Login to the router via its web interface (default password: admin)
2. Find the firmware update interface under "Connectivity/Basic"
3. Choose the OpenWrt factory image and click "Start"
4. If the router still boots into the stock firmware, it means that
the OpenWrt factory image has been installed to the secondary
partitions and failed to boot (since OpenWrt on EA4500 v3 does not
support dual boot yet), and the router switched back to the stock
firmware on the primary partitions. You have to install a stock
firmware (e.g. 3.1.6.172023, downloadable from
https://www.linksys.com/support-article?articleNum=148385 ) first
(to the secondary partitions) , and after that, install OpenWrt
factory image (to the primary partitions). After successful
installation of OpenWrt, auto_recovery will be automatically
disabled and router will only boot from the primary partitions.

- VCC (3.3V). Do not use unless you need to source power for the
converer from it.
- TX
- RX
- GND
Default port configuration in U-boot as well as in stock firmware is
115200-8-N-1.
Installation:
Due to different flash layout from stock firmware, sysupgrade from
within stock firmware is impossible, despite it's based on QSDK which
itself is based on OpenWrt.
STEP 0: Stock firmware update:
As installing OpenWrt cuts you off from official firmware updates for
the modem part, it is recommended to update the stock firmware to latest
version before installation, to have built-in modem at the latest firmware
version.
STEP 1: gaining root shell:
Method 1:
This works if busybox has telnetd compiled in the binary.
If this does not work, try method 2.
Using well-known exploit to start telnetd on your router - works
only if Busybox on stock firmware has telnetd included:
- Open stock firmware web interface
- Navigate to "URL filtering" section by going to "Advanced settings",
then "Firewall" and finally "URL filter".
- Add an entry ending with "&&telnetd&&", for example
"http://hostname/&&telnetd&&".
- telnetd will immediately listen on port 4719.
- After connecting to telnetd use "admin/admin" as credentials.
Method 2:
This works if busybox does not have telnetd compiled in. Notably, this
is the case in DNA.fi firmware.
If this does not work, try method 3.
- Set IP of your computer to 192.168.0.22. (or appropriate subnet if
changed)
- Have a TFTP server running at that address
- Download MIPS build of busybox including telnetd, for example from:
https://busybox.net/downloads/binaries/1.21.1/busybox-mips
and put it in it's root directory. Rename it as "telnetd".
- As previously, login to router's web UI and navigate to "URL
filtering"
- Using "Inspect" feature, extend "maxlength" property of the input
field named "addURLFilter", so it looks like this:
<input type="text" name="addURLFilter" id="addURLFilter" maxlength="332"
class="required form-control">
- Stay on the page - do not navigate anywhere
- Enter "http://aa&zte_debug.sh 192.168.0.22 telnetd" as a filter.
- Save the settings. This will download the telnetd binary over tftp and
execute it. You should be able to log in at port 23, using
"admin/admin" as credentials.
Method 3:
If the above doesn't work, use the serial console - it exposes root shell
directly without need for login. Some stock firmwares, notably one from
finnish DNA operator lack telnetd in their builds.
STEP 2: Backing up original software:
As the stock firmware may be customized by the carrier and is not
officially available in the Internet, IT IS IMPERATIVE to back up the
stock firmware, if you ever plan to returning to stock firmware.
It is highly recommended to perform backup using both methods, to avoid
hassle of reassembling firmware images in future, if a restore is
needed.
Method 1: after booting OpenWrt initramfs image via TFTP:
PLEASE NOTE: YOU CANNOT DO THIS IF USING INTERMEDIATE FIRMWARE FOR INSTALLATION.
- Dump stock firmware located on stock kernel and ubi partitions:
ssh root@192.168.1.1: cat /dev/mtd4 > mtd4_kernel.bin
ssh root@192.168.1.1: cat /dev/mtd9 > mtd9_ubi.bin
And keep them in a safe place, should a restore be needed in future.
Method 2: using stock firmware:
- Connect an external USB drive formatted with FAT or ext4 to the USB
port.
- The drive will be auto-mounted to /var/usb_disk
- Check the flash layout of the device:
cat /proc/mtd
It should show the following:
mtd0: 000a0000 00010000 "u-boot"
mtd1: 00020000 00010000 "u-boot-env"

mtd16: 01d00000 00020000 "firmware"
Differences might indicate that this is NOT a MF286A device but
one of other variants.
- Copy over all MTD partitions, for example by executing the following:
for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15; do cat /dev/mtd$i > \
/var/usb_disk/mtd$i; done
"Firmware" partition can be skipped, it is a concatenation
of "kernel" and "rootfs".
- If the count of MTD partitions is different, this might indicate that
this is not a MF286A device, but one of its other variants.
- (optionally) rename the files according to MTD partition names from
/proc/mtd
- Unmount the filesystem:
umount /var/usb_disk; sync
and then remove the drive.
- Store the files in safe place if you ever plan to return to stock
firmware. This is especially important, because stock firmware for
this device is not available officially, and is usually customized by
the mobile providers.
STEP 3: Booting initramfs image:
Method 1: using serial console (RECOMMENDED):
- Have TFTP server running, exposing the OpenWrt initramfs image, and
set your computer's IP address as 192.168.0.22. This is the default
expected by U-boot. You may wish to change that, and alter later
commands accordingly.
- Connect the serial console if you haven't done so already,
- Interrupt boot sequence by pressing any key in U-boot when prompted
- Use the following commands to boot OpenWrt initramfs through TFTP:
setenv serverip 192.168.0.22
setenv ipaddr 192.168.0.1
tftpboot 0x81000000 openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin
bootm 0x81000000
(Replace server IP and router IP as needed). There is no emergency
TFTP boot sequence triggered by buttons, contrary to MF283+.
- When OpenWrt initramfs finishes booting, proceed to actual
installation.
Method 2: using initramfs image as temporary boot kernel
This exploits the fact, that kernel and rootfs MTD devices are
consecutive on NAND flash, so from within stock image, an initramfs can
be written to this area and booted by U-boot on next reboot, because it
uses "nboot" command which isn't limited by kernel partition size.
- Download the initramfs-kernel.bin image
- After backing up the previous MTD contents, write the images to the
"firmware" MTD device, which conveniently concatenates "kernel" and
"rootfs" partitions that can fit the initramfs image:
nandwrite -p /dev/<firmware-mtd> \
/var/usb_disk/openwrt-ath79-zte_mf286a-initramfs-kernel.bin
- If write is OK, reboot the device, it will reboot to OpenWrt
initramfs:
reboot -f
- After rebooting, SSH into the device and use sysupgrade to perform
proper installation.
Method 3: using built-in TFTP recovery (LAST RESORT):
- With that method, ensure you have complete backup of system's NAND
flash first. It involves deliberately erasing the kernel.
- Download "-initramfs-kernel.bin" image for the device.
- Prepare the recovery image by prepending 8MB of zeroes to the image,
and name it root_uImage:
dd if=/dev/zero of=padding.bin bs=8M count=1
cat padding.bin openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin >
root_uImage
- Set up a TFTP server at 192.0.0.1/8. Router will use random address
from that range.
- Put the previously generated "root_uImage" into TFTP server root
directory.
- Deliberately erase "kernel" partition" using stock firmware after
taking backup. THIS IS POINT OF NO RETURN.
- Restart the device. U-boot will attempt flashing the recovery
initramfs image, which will let you perform actual installation using
sysupgrade. This might take a considerable time, sometimes the router
doesn't establish Ethernet link properly right after booting. Be
patient.
- After U-boot finishes flashing, the LEDs of switch ports will all
light up. At this moment, perform power-on reset, and wait for OpenWrt
initramfs to finish booting. Then proceed to actual installation.
STEP 4: Actual installation:
- Set your computer IP to 192.168.1.22/24
- scp the sysupgrade image to the device:
scp openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin \
root@192.168.1.1:/tmp/
- ssh into the device and execute sysupgrade:
sysupgrade -n /tmp/openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin
- Wait for router to reboot to full OpenWrt.
STEP 5: WAN connection establishment
Since the router is equipped with LTE modem as its main WAN interface, it
might be useful to connect to the Internet right away after
installation. To do so, please put the following entries in
/etc/config/network, replacing the specific configuration entries with
one needed for your ISP:
config interface 'wan'
option proto 'qmi'
option device '/dev/cdc-wdm0'
option auth '<auth>' # As required, usually 'none'
option pincode '<pin>' # If required by SIM
option apn '<apn>' # As required by ISP
option pdptype '<pdp>' # Typically 'ipv4', or 'ipv4v6' or 'ipv6'
For example, the following works for most polish ISPs
config interface 'wan'
option proto 'qmi'
option device '/dev/cdc-wdm0'
option auth 'none'
option apn 'internet'
option pdptype 'ipv4'
The required minimum is:
config interface 'wan'
option proto 'qmi'
option device '/dev/cdc-wdm0'
In this case, the modem will use last configured APN from stock
firmware - this should work out of the box, unless your SIM requires
PIN which can't be switched off.
If you have build with LuCI, installing luci-proto-qmi helps with this
task.
Restoring the stock firmware:
Preparation:
If you took your backup using stock firmware, you will need to
reassemble the partitions into images to be restored onto the flash. The
layout might differ from ISP to ISP, this example is based on generic stock
firmware
The only partitions you really care about are "web", "kernel", and
"rootfs". These are required to restore the stock firmware through
factory TFTP recovery.
Because kernel partition was enlarged, compared to stock
firmware, the kernel and rootfs MTDs don't align anymore, and you need
to carve out required data if you only have backup from stock FW:
- Prepare kernel image
cat mtd12_kernel.bin mtd13_rootfs.bin > owrt_kernel.bin
truncate -s 4M owrt_kernel_restore.bin
- Cut off first 1MB from rootfs
dd if=mtd13_rootfs.bin of=owrt_rootfs.bin bs=1M skip=1
- Prepare image to write to "ubi" meta-partition:
cat mtd6_reserved2.bi mtd7_cfg-param.bin mtd8_log.bin mtd9_oops.bin \
mtd10_reserved3.bin mtd11_web.bin owrt_rootfs.bin > \
owrt_ubi_ubi_restore.bin
You can skip the "fota" partition altogether,
it is used only for stock firmware update purposes and can be overwritten
safely anyway. The same is true for "data" partition which on my device
was found to be unused at all. Restoring mtd5_cfg-param.bin will restore
the stock firmware configuration you had before.
Method 1: Using initramfs:
This method is recmmended if you took your backup from within OpenWrt
initramfs, as the reassembly is not needed.
- Boot to initramfs as in step 3:
- Completely detach ubi0 partition using ubidetach /dev/ubi0_0
- Look up the kernel and ubi partitions in /proc/mtd
- Copy over the stock kernel image using scp to /tmp
- Erase kernel and restore stock kernel:
(scp mtd4_kernel.bin root@192.168.1.1:/tmp/)
mtd write <kernel_mtd> mtd4_kernel.bin
rm mtd4_kernel.bin
- Copy over the stock partition backups one-by-one using scp to /tmp, and
restore them individually. Otherwise you might run out of space in
tmpfs:
(scp mtd3_ubiconcat0.bin root@192.168.1.1:/tmp/)
mtd write <ubiconcat0_mtd> mtd3_ubiconcat0.bin
rm mtd3_ubiconcat0.bin
(scp mtd5_ubiconcat1.bin root@192.168.1.1:/tmp/)
mtd write <ubiconcat1_mtd> mtd5_ubiconcat1.bin
rm mtd5_ubiconcat1.bin
- If the write was correct, force a device reboot with
reboot -f
Method 2: Using live OpenWrt system (NOT RECOMMENDED):
- Prepare a USB flash drive contatining MTD backup files
- Ensure you have kmod-usb-storage and filesystem driver installed for
your drive
- Mount your flash drive
mkdir /tmp/usb
mount /dev/sda1 /tmp/usb
- Remount your UBI volume at /overlay to R/O
mount -o remount,ro /overlay
- Write back the kernel and ubi partitions from USB drive
cd /tmp/usb
mtd write mtd4_kernel.bin /dev/<kernel_mtd>
mtd write mtd9_ubi.bin /dev/<kernel_ubi>
- If everything went well, force a device reboot with
reboot -f
Last image may be truncated a bit due to lack of space in RAM, but this will happen over "fota"
MTD partition which may be safely erased after reboot anyway.
Method 3: using built-in TFTP recovery:
This method is recommended if you took backups using stock firmware.
- Assemble a recovery rootfs image from backup of stock partitions by
concatenating "web", "kernel", "rootfs" images dumped from the device,
as "root_uImage"
- Use it in place of "root_uImage" recovery initramfs image as in the
TFTP pre-installation method.
Quirks and known issuesa
- It was observed, that CH340-based USB-UART converters output garbage
during U-boot phase of system boot. At least CP2102 is known to work
properly.
- Kernel partition size is increased to 4MB compared to stock 3MB, to
accomodate future kernel updates - at this moment OpenWrt 5.10 kernel
image is at 2.5MB which is dangerously close to the limit. This has no
effect on booting the system - but keep that in mind when reassembling
an image to restore stock firmware.
- uqmi seems to be unable to change APN manually, so please use the one
you used before in stock firmware first. If you need to change it,
please use protocok '3g' to establish connection once, or use the
following command to change APN (and optionally IP type) manually:
echo -ne 'AT+CGDCONT=1,"IP","<apn>' > /dev/ttyUSB0
- The only usable LED as a "system LED" is the blue debug LED hidden
inside the case. All other LEDs are controlled by modem, on which the
router part has some influence only on Wi-Fi LED.
- Wi-Fi LED currently doesn't work while under OpenWrt, despite having
correct GPIO mapping. All other LEDs are controlled by modem,
including this one in stock firmware. GPIO19, mapped there only acts
as a gate, while the actual signal source seems to be 5GHz Wi-Fi
radio, however it seems it is not the LED exposed by ath10k as
ath10k-phy0.
- GPIO5 used for modem reset is a suicide switch, causing a hardware
reset of whole board, not only the modem. It is attached to
gpio-restart driver, to restart the modem on reboot as well, to ensure
QMI connectivity after reboot, which tends to fail otherwise.
- Modem, as in MF283+, exposes root shell over ADB - while not needed
for OpenWrt operation at all - have fun lurking around.
The same modem module is used as in older MF286.

The Zyxel EMG2926-Q10A is 99% the Zyxel NBG6716, but the bootloader
expects a different product name when flashing over TFTP. Also, the
EMG2926-Q10A always has 128 MiB of NAND flash whereas the NBG6716
reportedly can have either 128 MiB or 256 MiB.

Default port configuration in U-boot as well as in stock firmware is
115200-8-N-1.
Installation:
Due to different flash layout from stock firmware, sysupgrade from
within stock firmware is impossible, despite it's based on QSDK which
itself is based on OpenWrt.
STEP 0: Stock firmware update:
As installing OpenWrt cuts you off from official firmware updates for
the modem part, it is recommended to update the stock firmware to latest
version before installation, to have built-in modem at the latest firmware
version.
STEP 1: gaining root shell:
Method 1:
This works if busybox has telnetd compiled in the binary.
If this does not work, try method 2.
Using well-known exploit to start telnetd on your router - works
only if Busybox on stock firmware has telnetd included:
- Open stock firmware web interface
- Navigate to "URL filtering" section by going to "Advanced settings",
then "Firewall" and finally "URL filter".
- Add an entry ending with "&&telnetd&&", for example
"http://hostname/&&telnetd&&".
- telnetd will immediately listen on port 4719.
- After connecting to telnetd use "admin/admin" as credentials.
Method 2:
This works if busybox does not have telnetd compiled in. Notably, this
is the case in DNA.fi firmware.
If this does not work, try method 3.
- Set IP of your computer to 192.168.1.22.
- Have a TFTP server running at that address
- Download MIPS build of busybox including telnetd, for example from:
https://busybox.net/downloads/binaries/1.21.1/busybox-mips
and put it in it's root directory. Rename it as "telnetd".
- As previously, login to router's web UI and navigate to "URL
filtering"
- Using "Inspect" feature, extend "maxlength" property of the input
field named "addURLFilter", so it looks like this:
<input type="text" name="addURLFilter" id="addURLFilter" maxlength="332"
class="required form-control">
- Stay on the page - do not navigate anywhere
- Enter "http://aa&zte_debug.sh 192.168.1.22 telnetd" as a filter.
- Save the settings. This will download the telnetd binary over tftp and
execute it. You should be able to log in at port 23, using
"admin/admin" as credentials.
Method 3:
If the above doesn't work, use the serial console - it exposes root shell
directly without need for login. Some stock firmwares, notably one from
finnish DNA operator lack telnetd in their builds.
STEP 2: Backing up original software:
As the stock firmware may be customized by the carrier and is not
officially available in the Internet, IT IS IMPERATIVE to back up the
stock firmware, if you ever plan to returning to stock firmware.
Method 1: after booting OpenWrt initramfs image via TFTP:
PLEASE NOTE: YOU CANNOT DO THIS IF USING INTERMEDIATE FIRMWARE FOR INSTALLATION.
- Dump stock firmware located on stock kernel and ubi partitions:
ssh root@192.168.1.1: cat /dev/mtd4 > mtd4_kernel.bin
ssh root@192.168.1.1: cat /dev/mtd8 > mtd8_ubi.bin
And keep them in a safe place, should a restore be needed in future.
Method 2: using stock firmware:
- Connect an external USB drive formatted with FAT or ext4 to the USB
port.
- The drive will be auto-mounted to /var/usb_disk
- Check the flash layout of the device:
cat /proc/mtd
It should show the following:
mtd0: 00080000 00010000 "uboot"
mtd1: 00020000 00010000 "uboot-env"
mtd2: 00140000 00020000 "fota-flag"
mtd3: 00140000 00020000 "caldata"
mtd4: 00140000 00020000 "mac"
mtd5: 00600000 00020000 "cfg-param"
mtd6: 00140000 00020000 "oops"
mtd7: 00800000 00020000 "web"
mtd8: 00300000 00020000 "kernel"
mtd9: 01f00000 00020000 "rootfs"
mtd10: 01900000 00020000 "data"
mtd11: 03200000 00020000 "fota"
Differences might indicate that this is NOT a vanilla MF286 device but
one of its later derivatives.
- Copy over all MTD partitions, for example by executing the following:
for i in 0 1 2 3 4 5 6 7 8 9 10 11; do cat /dev/mtd$i > \
/var/usb_disk/mtd$i; done
- If the count of MTD partitions is different, this might indicate that
this is not a standard MF286 device, but one of its later derivatives.
- (optionally) rename the files according to MTD partition names from
/proc/mtd
- Unmount the filesystem:
umount /var/usb_disk; sync
and then remove the drive.
- Store the files in safe place if you ever plan to return to stock
firmware. This is especially important, because stock firmware for
this device is not available officially, and is usually customized by
the mobile providers.
STEP 3: Booting initramfs image:
Method 1: using serial console (RECOMMENDED):
- Have TFTP server running, exposing the OpenWrt initramfs image, and
set your computer's IP address as 192.168.1.22. This is the default
expected by U-boot. You may wish to change that, and alter later
commands accordingly.
- Connect the serial console if you haven't done so already,
- Interrupt boot sequence by pressing any key in U-boot when prompted
- Use the following commands to boot OpenWrt initramfs through TFTP:
setenv serverip 192.168.1.22
setenv ipaddr 192.168.1.1
tftpboot 0x81000000 openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin
bootm 0x81000000
(Replace server IP and router IP as needed). There is no emergency
TFTP boot sequence triggered by buttons, contrary to MF283+.
- When OpenWrt initramfs finishes booting, proceed to actual
installation.
Method 2: using initramfs image as temporary boot kernel
This exploits the fact, that kernel and rootfs MTD devices are
consecutive on NAND flash, so from within stock image, an initramfs can
be written to this area and booted by U-boot on next reboot, because it
uses "nboot" command which isn't limited by kernel partition size.
- Download the initramfs-kernel.bin image
- Split the image into two parts on 3MB partition size boundary, which
is the size of kernel partition. Pad the output of second file to
eraseblock size:
dd if=openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin \
bs=128k count=24 \
of=openwrt-ath79-zte_mf286-intermediate-kernel.bin
dd if=openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin \
bs=128k skip=24 conv=sync \
of=openwrt-ath79-zte_mf286-intermediate-rootfs.bin
- Copy over /usr/bin/flash_eraseall and /usr/bin/nandwrite utilities to
/tmp. This is CRITICAL for installation, as erasing rootfs will cut
you off from those tools on flash!
- After backing up the previous MTD contents, write the images to the
respective MTD devices:
/tmp/flash_eraseall /dev/<kernel-mtd>
/tmp/nandwrite /dev/<kernel-mtd> \
/var/usb_disk/openwrt-ath79-zte_mf286-intermediate-kernel.bin
/tmp/flash_eraseall /dev/<kernel-mtd>
/tmp/nandwrite /dev/<rootfs-mtd> \
/var/usb_disk/openwrt-ath79-zte_mf286-intermediate-rootfs.bin
- Ensure that no bad blocks were present on the devices while writing.
If they were present, you may need to vary the split between
kernel and rootfs parts, so U-boot reads a valid uImage after skipping
the bad blocks. If it fails, you will be left with method 3 (below).
- If write is OK, reboot the device, it will reboot to OpenWrt
initramfs:
reboot -f
- After rebooting, SSH into the device and use sysupgrade to perform
proper installation.
Method 3: using built-in TFTP recovery (LAST RESORT):
- With that method, ensure you have complete backup of system's NAND
flash first. It involves deliberately erasing the kernel.

and name it root_uImage:
dd if=/dev/zero of=padding.bin bs=8M count=1
cat padding.bin openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin >
root_uImage
- Set up a TFTP server at 192.0.0.1/8. Router will use random address
from that range.
- Put the previously generated "root_uImage" into TFTP server root
directory.
- Deliberately erase "kernel" partition" using stock firmware after
taking backup. THIS IS POINT OF NO RETURN.
- Restart the device. U-boot will attempt flashing the recovery
initramfs image, which will let you perform actual installation using
sysupgrade. This might take a considerable time, sometimes the router
doesn't establish Ethernet link properly right after booting. Be
patient.
- After U-boot finishes flashing, the LEDs of switch ports will all
light up. At this moment, perform power-on reset, and wait for OpenWrt
initramfs to finish booting. Then proceed to actual installation.
STEP 4: Actual installation:
- scp the sysupgrade image to the device:
scp openwrt-ath79-nand-zte_mf286-squashfs-sysupgrade.bin \
root@192.168.1.1:/tmp/
- ssh into the device and execute sysupgrade:
sysupgrade -n /tmp/openwrt-ath79-nand-zte_mf286-squashfs-sysupgrade.bin
- Wait for router to reboot to full OpenWrt.
STEP 5: WAN connection establishment
Since the router is equipped with LTE modem as its main WAN interface, it
might be useful to connect to the Internet right away after
installation. To do so, please put the following entries in
/etc/config/network, replacing the specific configuration entries with

option proto 'qmi'
option device '/dev/cdc-wdm0'
option auth '<auth>' # As required, usually 'none'
option pincode '<pin>' # If required by SIM
option apn '<apn>' # As required by ISP
option pdptype '<pdp>' # Typically 'ipv4', or 'ipv4v6' or 'ipv6'
For example, the following works for most polish ISPs
config interface 'wan'
option proto 'qmi'
option device '/dev/cdc-wdm0'
option auth 'none'
option apn 'internet'
option pdptype 'ipv4'
If you have build with LuCI, installing luci-proto-qmi helps with this
task.
Restoring the stock firmware:
Preparation:
If you took your backup using stock firmware, you will need to
reassemble the partitions into images to be restored onto the flash. The
layout might differ from ISP to ISP, this example is based on generic stock
firmware.
The only partitions you really care about are "web", "kernel", and
"rootfs". For easy padding and possibly restoring configuration, you can
concatenate most of them into images written into "ubi" meta-partition
in OpenWrt. To do so, execute something like:
cat mtd5_cfg-param.bin mtd6-oops.bin mtd7-web.bin mtd9-rootfs.bin > \
mtd8-ubi_restore.bin
You can skip the "fota" partition altogether,
it is used only for stock firmware update purposes and can be overwritten
safely anyway. The same is true for "data" partition which on my device
was found to be unused at all. Restoring mtd5_cfg-param.bin will restore
the stock firmware configuration you had before.
Method 1: Using initramfs:
- Boot to initramfs as in step 3:
- Completely detach ubi0 partition using ubidetach /dev/ubi0_0
- Look up the kernel and ubi partitions in /proc/mtd

rm mtd4_kernel.bin
- Copy over the stock partition backups one-by-one using scp to /tmp, and
restore them individually. Otherwise you might run out of space in
tmpfs:
(scp mtd3_ubiconcat0.bin root@192.168.1.1:/tmp/)
mtd write <ubiconcat0_mtd> mtd3_ubiconcat0.bin
rm mtd3_ubiconcat0.bin
(scp mtd5_ubiconcat1.bin root@192.168.1.1:/tmp/)
mtd write <ubiconcat1_mtd> mtd5_ubiconcat1.bin
rm mtd5_ubiconcat1.bin
- If the write was correct, force a device reboot with
reboot -f
Method 2: Using live OpenWrt system (NOT RECOMMENDED):
- Prepare a USB flash drive contatining MTD backup files
- Ensure you have kmod-usb-storage and filesystem driver installed for
your drive
- Mount your flash drive
mkdir /tmp/usb
mount /dev/sda1 /tmp/usb
- Remount your UBI volume at /overlay to R/O
mount -o remount,ro /overlay
- Write back the kernel and ubi partitions from USB drive
cd /tmp/usb
mtd write mtd4_kernel.bin /dev/<kernel_mtd>
mtd write mtd8_ubi.bin /dev/<kernel_ubi>
- If everything went well, force a device reboot with
reboot -f
Last image may be truncated a bit due to lack of space in RAM, but this will happen over "fota"
MTD partition which may be safely erased after reboot anyway.
Method 3: using built-in TFTP recovery (LAST RESORT):
- Assemble a recovery rootfs image from backup of stock partitions by
concatenating "web", "kernel", "rootfs" images dumped from the device,
as "root_uImage"
- Use it in place of "root_uImage" recovery initramfs image as in the
TFTP pre-installation method.
Quirks and known issues
- Kernel partition size is increased to 4MB compared to stock 3MB, to
accomodate future kernel updates - at this moment OpenWrt 5.10 kernel
image is at 2.5MB which is dangerously close to the limit. This has no
effect on booting the system - but keep that in mind when reassembling
an image to restore stock firmware.
- uqmi seems to be unable to change APN manually, so please use the one
you used before in stock firmware first. If you need to change it,
please use protocok '3g' to establish connection once, or use the
following command to change APN (and optionally IP type) manually:
echo -ne 'AT+CGDCONT=1,"IP","<apn>' > /dev/ttyUSB0
- The only usable LED as a "system LED" is the green debug LED hidden
inside the case. All other LEDs are controlled by modem, on which the
router part has some influence only on Wi-Fi LED.
- Wi-Fi LED currently doesn't work while under OpenWrt, despite having
correct GPIO mapping. All other LEDs are controlled by modem,
including this one in stock firmware. GPIO19, mapped there only acts
as a gate, while the actual signal source seems to be 5GHz Wi-Fi
radio, however it seems it is not the LED exposed by ath10k as
ath10k-phy0.
- GPIO5 used for modem reset is a suicide switch, causing a hardware
reset of whole board, not only the modem. It is attached to
gpio-restart driver, to restart the modem on reboot as well, to ensure
QMI connectivity after reboot, which tends to fail otherwise.
- Modem, as in MF283+, exposes root shell over ADB - while not needed
for OpenWrt operation at all - have fun lurking around.
- MAC address shift for 5GHz Wi-Fi used in stock firmware is
0x320000000000, which is impossible to encode in the device tree, so I
took the liberty of using MAC address increment of 1 for it, to ensure
different BSSID for both Wi-Fi interfaces.

Since gzip-compressed kernel image stopped fitting on 4MB kernel
partition on the device, use lzma-loader wrapping LZMA-compressed
kernel. This yields bootable device once again, and saves a very
substantial amount of space, the kernel size decreasing from about 4.4MB
to about 2.5MB for 5.10 kernel. This avoids changing of the flash layout
for the device.
While at that, reactivate the build for the device.

Netgear R6100 is a dual-band Wi-Fi 5 (AC1200) router based on Qualcomm
Atheros (AR9344 + QCA9882) platform. Support for this device was first
introduced in 15f6f67d18 (ar71xx). FCC ID: PY312400225.
Specifications:
- Atheros AR9344 (560 MHz)
- 128 MB of RAM (DDR2)
- 128 MB of flash (parallel NAND)
- 2T2R 2.4 GHz Wi-Fi (AR9344)
- 2T2R 5 GHz Wi-Fi (QCA9882)
- 5x 10/100 Mbps Ethernet (AR9344)
- 4x internal antenna
- 1x USB 2.0 (GPIO-controlled power)
- 6x LED, 3x button (reset, Wi-Fi, WPS)
- UART (4-pin, 2.54 mm pitch) header on PCB
- 1x mechanical power switch
- DC jack for main power input (12 V)
WARNING: sysupgrade from older stable releases is not possible, fresh
installation (via vendor's GUI or TFTP based recovery) is required.
Reason for that is increased kernel partition size.
Installation:
Use the 'factory' image under vendor's GUI or via TFTP U-Boot recovery.
You can use the 'nmrpflash' tool at a boot time, before kernel is loaded
or start it manually by pressing the 'reset' button for ~20 seconds from
powering up the device (U-Boot will start TFTP server on 192.168.1.1,
use TFTP client to send the image).

MAC addresses based on vendor firmware:
LAN *:a0 art 0x0
2.4GHz *:a1 art 0x1002
5GHz *:a2 art calculated from art 0x0 + 2
Flash firmware:
Since openwrt's kernel already exceeds 2MB, upgrading from the official
version of GL-inet (v3.100) using the sysupgrade command will break the
kernel image. Users who are using version 3.100 can only upgrade via
uboot. The official guidance for GL-inet is as follows:
https://docs.gl-inet.com/en/3/troubleshooting/debrick/
In the future, GL-inet will modify the firmware to support the sysupgrade
command, so users will be able to upgrade directly with the sysupgrade
command in future releases.
OLED screen control:
OLED controller is connected to QCA9531 through serial port, and can send
instructions to OLED controller directly through serial port.

Important Notes
===============
0. NOR Flash (2 MiB) is not touched by OpenWrt installation.
1. NAND Flash (128 MiB) layout under OpenWrt is changed as follows:
all space is split between 4 MiB kernel and 124 MiB UBI areas;
vendor partitions (language and mtdoops) are removed; kernel space
size can be further expanded if needed; maximum image size is set
to 25600k for compatibility reasons and can also be increased.
2. CPU clock is 775 MHz, not 750 MHz.
3. 5 GHz wireless radio chip is Atheros AR9580-AR1A with bogus PCI
device ID 0xabcd. For ath9k driver to load successfully, this is
overriden in DTS with correct value for this chip, 0x0033.
4. RFKILL button is wired to AR9580 pin 9 which is normally disabled
by chip definition in ath9k code (0x0000F4FF gpio mask). Therefore
'qca,gpio-mask=<0xf6ff>' hack must be used for button to work
properly.
5. USB port is always on, no GPIO for 5V power control has been
identified.
